This quick experimental PR generalizes Optional to support non-escapable payloads, itself becoming conditionally escapable.

Can we get the ExpressibleByNilLiteral and init(_ wrapped: consuming Wrapped) initializer supported?

For ExpressibleByNilLiteral, I believe we still need to figure out how to express indefinite lifetime for the result of the init(nilLiteral:) initializer.
